The question is whether the extension will be as steep. The incline of the existing North Stand lower tier (annoying hosting parents with children) will not change - with an incline of just under 10º. The existing second tier, has an incline of around 15º. Clearly, if they extend the second tier to the spec provided by the club, you would expect this to stay the same. To give some context, the incline of the South Stand Level 3, which is a new tier altogether - is just under 25º (pretty steep). Everton’s new stadium is proposed at 12º, which is on par with St Mary’s and the King Power. Although that stand behind the goal looks well above 30º in the specs!
